Requesting OS level spellcheck.  I currently observe no spellcheck in the MacOS version on Mojave.

I think I could make this work on Mac, though it might impact the performance of the chat text input. It's pretty much impossible on Windows and Linux, since there's no consistent way to access dictionaries on those platforms, and I'm not going to ship a multilingual dictionary with Ripcord.

I'll have to do some research and see how hard it is on Mac. I suspect that actually checking the spelling of strings is easy, but having the popup panels and stuff for applying corrections and further user interaction is much more difficult, since Ripcord isn't built from Cocoa widgets.

This would be a really nice feature to have.
I know there are a few libraries out there that could probably be integrate with even if it required people to download their own dictionaries.
